SHUTTLE.

Speccation of Letters Patent. Patented Dec. 28, 1909.

Application filed January 2, 1909. Serial No. 470,474.

To all whom it may concern:

Be it known that I, PnlLirrE GAUTHIER, a subject of the King of Great Britain, re- -sidingl at' Lowell, county of Middlesex, and State of i\lassaehnsetts, have invented an Iinl'n'oveuleut in Shuttles, of which the following'description, in connection with the `acconipanyingdrawings, is a specification, likefnumerals on the drawings representing like parts.

The invention to be hereinafter described relates to shuttles and more particnlarlyto the tension means employed to controlthe thread delivery as the shuttle passes through the shed.

The object of the invention is to provide a shuttle with al simple and etlicient tension means, which shall maintain deliverable control for uniform tension on the yarn or thread during the tlightof the shuttle irrespective of changes in the surrounding conditions of use.

The aims and purposes of the invention ',will'be best madeI clear from, the following descriptionand accompanying drawings of one form or embodiment of the invention which in its true scope is hereinafter detihitely pointed out in the claims. l

In the drawings :-l"igure l is a plan view Oof one end of a shuttle having the presentinvention associated therewith; Fig. l is a central longitudinal -section on the line 2 2, Fig. l; Fig. 3 is a View of the threading block detached fromv theshuttleV and looking at the under portion ofthe block; Fig. 4f an end'viewof the threading block looking in the direction of theI arrow, a, Fig. 3; Fig. t) an end view looking in the direction of theA arrow. t), Eig. l; Fig. t3 is a section on 40 the'line o o, Fig. 3; V'and Fig. 7 is-a per spectrive view of the ibrons n laterial vdctach'ed and showing its general form when @i'nposition ou the threading block.

The shuttle l may be of any usual or preferred form and construction to carry a bobvbin 2, and is herein shown as of the selfthreading type having a thread delivery er@ 3- The threading block may be of usual and well understood construction adapted for aucasting l having side walls 5;.and (3 between.

which is the threading slot T, said walls 5 and 6 preferablyv extending forward to form the cooperating portion S and beak 9. The block l is supported in a proper seat formed in the shuttle body, and provided with a base pin or stud l0 which engages a recess in the shuttle, as indicated, and a bolt ll passing through a hole in the block and into the shuttle body secures the threading block in place.

Extending longitudinally of the threading block is the supporting vall l?. for the fibrous tension material 13, Figs. t3 and T, said wall lf2 being preferablyv trough shaped in cross` section, as indicated in Fig. et, whereby the fibrous strip of material extending along the suplriorting wall has its` side portions` turned upward, as at ll, to form, in-ellect, a iibrous passage-nay for the yarn or thread passing from the bobbin to the delivery eye, said supporting wall l2 and the iibrous passage-way being preferably, though notof necessity, inclined downwardly from the rear toward the front of the threading block.

The threading block ma have a .shield o s f .l l guard 15 extending along one of its .side walls. projecting transversely and down* wardly, Figs. l and et, to prevent accidental displacement. of the yarn or thread by upward movement thereof from its .fibrous pa'ssage-way.

As well understood by those skilled in the art the sudden start and stop of the shuttle during weaving is liable to loosen any ordinary holding` means for the fibrous tension materiahsuch as screws, bolts, or the like, and one phase of the present .invention contemplates holding means for the fibrous material quite free from such objections and which Will securely maint-ain said inateri 1l sov wardly projecting portion 16, Figs. 1, 2, 4 A

and 6, connected to the threading block by a bridge or wall 17, said portion 16 being recessed at its upper end 18, Fig. 4, in general conormity'with the cross-sectional con- -tour of ther supporting wall 1 2, and being separated from the main body of the threading bloclr to form a holding notch into which a portion of the fibrous material extends, as will presently appear.

The fibrous tension material is preferably formed as a strip. of felt or the like 13, Fig. 7, which may readily conform to the trough-like contour of the supporting wall 12, and is bent reversely at 19, Fig. 7 with the end 2O disposed between the bends, the construction and arrangement `being such that the reversely bent portion and end 20 may be readily forced into the space between the projecting portion 16 and 'main body f of the threading block. At the bend 21, Fig.

7, the fibrous material is provided with removed portion or perforation 22, which, when the material is bent as shown, forms a continuation of the trough-like contour of the fibrous passage-way permitting the yarn or thread, as it comes from the bobbln 2, to assume direction into the bottom of the fibrous passage-way through the blockv and a'ct, in a measure, as a threading or guiding eye disposed at the rear end of the block. A t the exit end of the passageway the fibrous material is carried-down over the front Wall 23, Fig. 6, of the block, and near its end portionis provided with a perforation 24 to engage the stud or pin 10, whereby this end of the material is secured.

Projecting down from the threading block 4 at the delivery side of the fibrous passageway is a. guiding pin 25I about which the yarn or thread turns on its way to the delivery eye 3, thereby obviating any Wear upon the fibrous material at this point incident to chang; in direction of travel of the yarn or thr'ea From the construction described it will be noted that the fibrous tension material Iextends from the point of entrance to the point of' eXit of the yarn or thread through the threading block, and between said points it forms, by its trough-like contour, a fibrous passage-way for the yarn or thread Which is thus insured proper tension without liability `of being thrown from the influence of the tension material by the'action of thgshuttle While the invention has been described a's associated with a particular form of threading block, such form of threading blockis not essential, and indeed, under proper formation of the shuttle walls, it will be at once apparent that the essentials of the invention may be appropriated in other shuttle structures.

What is claimed is:

1. A shuttle having a threading block provided With a thread passage, and a strip of fibrous material having a trough-like texision surface extending throughout the length of the thread passage.

2. A shuttle having a threading block provided with a thread passage, a strip of fibrous material having a trough-like tension surface extending throughout the length of the 'thread passage, and means for securing said fibrous materlal in place.

3. A shuttle having a threading block provided with a thread passage, a strip of fibrous material having a trough-like tension surface extending throughout the lengthof the thread passage, and means for securing the end portions of said fibrous strips l to said block.
